EditGraph Method

Summary

Registers the current graph and runs the DirectShow GraphEdit utility.

Syntax

C++/CLI

public virtual void EditGraph()

public: 
virtual void EditGraph();

Remarks

This method displays a modal dialog box indicating that the graph has been registered. The current thread is suspended during this time. The toolkit then attempts to invoke the GraphEdit utility from the DirectShow SDK. Use GraphEdit's "Connect" menu option to view the registered graph. When finished, exit GraphEdit, and click on the dialog's OK button to continue program execution.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public PlayCtrlForm _form = new PlayCtrlForm(); 
 
public void EditGraphExample() 
{ 
   // reference the convert control 
   PlayCtrl playctrl = _form.PlayCtrl; 
 
   // input file name 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "PlayCtrl_Source.mpeg"); 
 
   try 
   { 
      // turn off auto start 
      playctrl.AutoStart = false; 
 
      // set the source and target files 
      playctrl.SourceFile = inFile; 
 
      // register the graph for GraphEdit  
      // you should see a message box that says the graph is registered  
      // once this message displays you can open GraphEdit and Connect to Remote Graph 
      playctrl.EditGraph(); 
 
      // play it! 
      playctrl.Run(); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
 
   // we'll loop on the state and pump messages for this example. 
   // but you should not need to if running from a Windows Forms application. 
   while (playctrl.State == PlayState.Running) 
      Application.DoEvents(); 
 
   // set the result 
   _result = true; 
} 
 
static class LEAD_VARS 
{ 
   public const string MediaDir = @"C:\LEADTOOLS23\Media";
